Run JRuby on Heroku Right Now

Over a year ago Heroku launched the Cedar stack and the ability to run Java on our platform . Java is known as a powerful language – capable of performing at large scale. Much of this potential comes from the JVM that Java runs on. The JVM is the stable, optimized, cross-platform virtual machine that also powers other languages including Scala and Clojure. Starting today you can leverage the power of the JVM in your Ruby applications without learning a new language, by using JRuby on Heroku.

After a beta process with several large production applications,…

Postgres 9.2 – The Database You Helped Build

Hosting your data on one of the largest fleets of databases in the world comes with certain advantages. One of those benefits is that we can aggregate the collective pain points that face our users and work within the Postgres community to help find solutions to them.

In the previous year we worked very closely with the broader Postgres community to build features, fix bugs, and resolve pain points. You've already seen some of the results of that work in the form of extension support on Heroku and query cancellation . With the 9.2 release we're delighted to…

Presenting the New Add-ons Site

We also briefly covered some of the end-user customizations that can be achieved with custom buildpacks, such as adding binary support and modifying the build process.

Today we'll examine…

Fork Your Application’s Data (Not Just Your Code)

Git and Github revolutionized software development by letting you fork your source repository with a single click. Wouldn't it be great to be able to do the same thing with your database?

In the same way you can fork your code you can now fork your data. Fork changes the way you can work with your data, making it a snap to provision a clone of your production database. The technology is simple, safe, and robust, and thanks to Heroku Postgres' cloud architecture, places no load on your primary database. Today, we’re announcing the release of this functionality…
